I can take care of this if time is an issue for you. I just need your approval/confirmation from you.
Please let us know so another 1.9.3 release goes out with this broken behavior.
Nakada-san,
I think this issue should be fixed before 1.9.3 release. I hope 1.9.3
has no regression.
This issue was solved with changeset r33165.
Luis, thank you for reporting this issue.
Your contribution to Ruby is greatly appreciated.
May Ruby be with you.
